Batch & Lot Traceability for Infant Formula Buyers
Quick answer: batch and lot traceability means being able to connect a specific product unit or case to identifying production information and the businesses that handled it. For formula buyers, recording SKU, lot/batch code, date marking, supplier and receiving details can make recalls and investigations faster and more targeted.
What is a lot or batch code?
A lot or batch code is an identifier assigned to a defined production lot. FDA describes a traceability lot code as a descriptor—often alphanumeric—used to uniquely identify a traceability lot within relevant records.
Why traceability matters for infant formula
Infant formula is a highly controlled food category. When a manufacturer or authority investigates a problem, accurate batch information helps determine whether a specific unit or case is within the affected scope.
FDA also advises case buyers to check that lot numbers and use-by dates on containers and boxes match.

| Data field | Example use |
|---|---|
| SKU / product title | Identifies the exact formula and stage |
| Supplier | Identifies where the stock was sourced |
| Lot / batch code | Links stock to a production lot |
| Use-by / expiry date | Supports rotation and validity checks |
| Quantity received | Defines exposure by batch |
| Receiving date | Supports inventory history |
Traceability and FEFO solve different problems
FEFO inventory management helps decide which valid stock should move first. Traceability helps identify where a specific batch came from and where it went. A strong inventory process uses both.
What to do if batch information does not match
If an outer case and inner boxes show inconsistent lot or date information, stop the affected stock from being sold or dispatched until the discrepancy is understood. Photograph the labels and contact the supplier with the order details.
How traceability helps during a recall
- Identify the affected product and lot range.
- Search receiving records for that lot.
- Locate remaining stock.
- Identify downstream orders where records allow.
- Follow manufacturer or authority instructions for hold, return or disposal.
Link receiving records to outgoing orders where practical
Traceability becomes more useful when a business can move in both directions: from supplier receipt to a specific lot, and from that lot to downstream customer orders where the system supports it. This can reduce the scope of a recall response compared with treating all stock of a product as affected.
Preserve evidence when a discrepancy appears
If batch, date or packaging information looks inconsistent, keep photographs of the outer case and representative inner boxes together with the purchase order and receiving record. Do not overwrite the original data while investigating the discrepancy.
Traceability supports authenticity checks but does not replace them
A coherent lot history, supplier record and matching case information can support confidence in the supply chain. However, authenticity may also require manufacturer verification, authorized-distribution information or regulatory checks. Lot data is one evidence layer, not a complete authenticity certificate.

Frequently asked questions
Is a lot code the same as an expiry date?
No. They serve different purposes. A lot code identifies a production lot; an expiry or use-by date indicates the product's date marking.
Should retailers record batch codes?
Recordkeeping requirements vary by jurisdiction and business. From an operational perspective, retaining relevant batch information can make investigations and recalls more precise.
Can traceability prove a product is authentic?
Traceability records can support product history, but authenticity verification may require additional manufacturer, supplier or regulatory checks.
